Buying altcoin is certainly better when the price is cheap, and in my opinion now is the right time to buy altcoins, I always believe that the market will soon recover so that someday the market can make us get big profits.
indeed if the price of the altcoin goes down it is a good thing to buy it, because if we buy it when prices go down and we wait patiently for the price of the altcoin to rise, we can definitely get a lot of profit.
in my opinion there are good coins in the altcoin and good potential, if we invest in the coins, I'm sure we can definitely make a profit even though market conditions sometimes rise and fall, but believe the market will rise again.
